Default Error Code 1495

As stated in the title have error code 1495 and cannot find the meaning in the sticky provided. Also have a 420 (catalyst system low) and 462 (fuel level circ low volt) code that I could use some thoughts on. Gas gauge has just works when it wants.

P1495-LEAK DETECTION PUMP SOLENOID CIRCUIT

SET CONDITION
The state of the solenoid circuit does not match the PCM's desired state.

POSSIBLE CAUSES
Wiring Harness Intermittent
Leak Detection Pump
Fused Ignition Switch Output
LDP Solenoid Control Circuit Shorted To Ground
LDP Solenoid Control Circuit Open
PCM

Leak Detection Pump System
The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. Government regulations require on-board testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. During self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

============================

P0420 is a possible downstream 02 sensor located by the CAT.

============================

P0462 Possible bad fuel level sending unit.
